The Finnøy Engine
The first one ...
Nils N. Finnøy Motorfabrik was founded by Nils N. Finnøy in 1903. He made the first engine on Finnøya. The very first engines were four-stroke engine gases, but after a while they passed over to four-stroke glowhole motors. and in 1906 he went over to two-stroke glowhole motors.
The first fortunes drew Finnøy production on a small scale, but around 1910-1912 demand was so high that production was expanding and in 1915 there was a built-in iron jumper.
